Ethernet PHY allows use of UTP in automotive, industrial environments

December 10, 2015 // By Graham Prophet
Microchip’s KSZ8061 Quiet-WIRE technology 10/100BASE-TX Ethernet physical-layer transceivers provide reduced line emissions and superior receiver immunity over unshielded cabling, meeting automotive and industrial EMC requirements.

The KSZ8061 single-chip 10BASE-T/100BASE-TX automotive- and industrial-grade Ethernet physical-layer transceiver is designed for data communication over low-cost Unshielded Twisted Pair (UTP) cables. It is the first of a family based on the patented and programmable Quiet-WIRE enhanced EMC technology, providing reduced line emissions and superior receiver immunity performance. System reliability is also enhanced with Microchip’s proven LinkMD+ advanced cable diagnostics in addition to an embedded signal-quality indicator for the dynamic monitoring of link error margins.

For energy-efficient applications, Microchip’s integrated EtherGREEN technology includes an Ultra Deep Sleep mode with signal-detect wakeup, which lowers standby power consumption to the sub-microampere range.

With fast boot and linkup in less than 20 msec, the KSZ8061 is suitable for applications where startup time is critical, such as automotive rear-view cameras. The KSZ8061 family is available with an extended temperature range of -40 to +105 C for harsh-environment applications, including industrial sensor networks, robotics, building automation and avionics. This Ethernet PHY transceiver family provides support for both the MII and RMII processor interfaces, for easy integration with numerous processors, MCUs and SoCs.

An evaluation board, to enable functional and performance testing of the KSZ8061, the KSZ8061MNX Evaluation Board (KSZ8061MNX-EVAL) is available now for pre-orders, with delivery in January 2016, at $115.00.

Packaging options include 32-pin, 5 x 5 mm and 48-pin, 6 x 6 mm QFN packages.
